THOMAS B. WILKINSON, OF NEW YORK, N. Y.

DOOR-SEGURER.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed January 9,1907. Serial No. 351,487.

between the edge of the door and the door jamb, and

it has for its purpose to produce a device of this character, of asimple and economical construction, that can be readily carried in thepocket and which can be quickly and effectively applied for use in adark room, and without injuring the door or the jamb.

With the above objects in view and other objects hereinafter made clear,my invention consists in a door securer embodying the peculiar and novelconstruction of parts, hereinafter fully described, specifically pointedout in the claims and illustrated in the accompanying drawings, in whichFigure 1, is a perspective view of a portion of a door and door jamb,with my device applied for use. Fig. 2, is a horizontal section thereof,taken substantially on the line 22 of Fig. 1. Fig. 3, is a viewillustrating the manner in which the lock washer or ring is slipped ontothe notch plate. Fig. 4, is a cross section on the line 44 of Fig. 2,showing the position of the lock washer when adjusted for locking theparts together. Fig. 5, is a detail perspective view of the two partsconstituting the complete device, separated. Fig. (5, illustrates aslightly modified form of the notched plate, hereinafter again referredto. i

In the practical construction, my improved door securer consists of twoparts, the notched plate 1 and the lock washer or ring 2. The platel isstamped up or otherwise formed of a flat thin steel member, one end ofwhich is bent at right angles to form an end flange 10, which, in theapplication of the device, is intended to fit into the lock bolt mortise3 in the door jamb, as shown in Fig. 2. In doors that have no insidelock bolts, the said flange may be sharpened and provided with spurs 10as shown in Fig. 6, whereby such end may be easily forced into the jamb.

The opposite edges of the plate 1 are formed with a series of notches 10suitably spaced apart, the opposite sides being notched so the plate canbe used for right and left opening doors.

The lock ring or washer 2 has a central opening 20 of a diametersuflicient to fit over the narrow or shank portion 10 of the plate 1 andwhich also has a slit 20 at one edge that extends to the opening 20, thesaid slit being just wide enough to permit of slipping the washeredgewise over the shank 10 the construction of the washer being suchthat when slipped on the shank and located in the desired one of thenotches, it can be readily turned on the said shank. The washer 2 isalso provided with a notch 20 at the inner edge of its opening, whichnotch has a width suificient to permit the washer, when it is turneduntil the notch is in line with the edge of the shank 10, to drop downon the shank and thereby lock the washer from turning on the shank andcause it to act as a stop to project over the door edge, see Fig. l, andhold the door from being opened.

I am aware that notched plates have heretofore been provided forslipping between the door and jamb, which have had one end formed topenetrate the door jamb or casing and the outer end especially shaped toreceive slide keys or similar detent devices. My invention differs, sofar as I know, in the special construction of my lock ring or washer,since in my invention, by providing the slitted washer, the same can beinstantly slipped over the notch shank close up to the doorand can bereadily turned to bring its lock into register with the edge of thenotch shank.

By making the lock or detent in the nature of a washer or ring, it willbe automatically sustained in its locking position by gravity, since thewidth thereof is balanced and hence danger of the said washer beingjumped or jarred to disengage it from the shank, is reduced to theminimum.

To release the securer, it is only necessary to shove the ring up tolift the notch off the shank and giving the ring a quarter turn to bringits slit in line with the flat plate when it can be readily slipped offedgewise.

By reason of providing the lock washer as shown, no special manipulationof the washer is required to ad just the parts, since the said washercan be so easily manipulated that it can be quickly applied for use in adark as well as a light room.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

A door securer, comprising a flat plate having one end bent laterallyand having" each of its. opposite edges formed with a series of uniformnotches; in combination with a washer having a single opening, of adiameter slightly greater than the width of the plate between theopposing notches, said washer having a slit in one edge extending" toits opening, and having a notch on its internal edge at a point at rightangles to the slit, for the purposes described.
